Common causes of backfires are:
Poor or unregulated engine timing is often a cause of intake backfires, but can also be responsible for exhaust backfires
Improper wiring in the ignition can also lead to timing issues and backfires
Low fuel pressure, clogged fuel filters, and weak fuel pumps could cause a severe lean air-to-fuel ratio during fuel injection
Missing or damaged catalytic converter can result in backfires out the tailpipe
Air injection problem/diverter valve/check valve
